why doesn't it land in may catch

[Maersa]

Hi,

I have the following code, but can't catch the exception..

try
{
Int32 v =
(Int32)TypeDescriptor.GetConverter(typeof(int32)).ConvertFromString(
"test" );
// Int32 v = Convert.ToInt32( "test" );
}
catch( Exception e )
{
throw new Exception( e.Message, e );
}

Appreciate your help.

thanks,

Try Int32.Parse("test") instead of Convert.ToInt32 and see if it works

The same result, since Convert.ToInt32() internally calls Int32.Parse()....
:-(

When you say "test" I suppose the string is something like "1234" ..... ?
if you really use the string "test", of course it won't work

Yes, that's why I got the try...catch ... but the exception thrown by
Int32.Parser can't be "caught"....

The code below doesn't compile - the fragment typeof(int32) should be
typeof(Int32).

Once I changed that it ran and threw an exception which was caught.
The line
// Int32 v = Convert.ToInt32( "test" );
wont throw an exception because you've got it commented out - it never
compiled into IL.

If you uncomment that line and comment out the line above it it wil throw an
exception which is caught.

You must not be testing your code correctly.

Could you produce a short but complete program to demonstrate this? See
http://www.pobox.com/~skeet/csharp/complete.html for what I mean by
that.
